A hoverboard toy was left on charge and caught alight.
Two fire engines were sent to the home in Acorn Close, Tonbridge, and crews wore breathing apparatus while using hose reel jets to extinguish the fire, which broke out on the ground floor of the house.
The house fire is believed to have started accidentally when a hoverboard toy was left on charge and caught alight.
Firefighters, who used a high pressured fan to clear the house of smoke, also rescued a hamster and pet fish from the property.
The occupants were not at home at the time of the fire and no other casualties were reported.
